Abstract: An apparatus, computer-readable medium, and computer-implemented method for detecting user presence includes receiving an identifier code from a user device, the identifier code being associated with a transmitter, determining a location of the transmitter based at least in part on the identifier code, and determining that a user associated with the user device is near the location of the transmitter.

Abstract: A position input device includes a conductive resistive sheet as a sensing element and at least four terminals on the conductive sheet which are spaced apart from each other. The four terminals received oscillating electric field signals that correspond to the three dimensional position of a pointing object based on a capacitive coupling of the pointing object to the conductive sheet. A processor generates the three dimensional position data of the pointing object hovering over the conductive sheet based on oscillating output signals from the four terminals.

Abstract: A system for sensing the position of a pointer with respect to a reference frame is described wherein the system has a sensing device capable of measuring an electric field around the pointer when it is in proximity to the reference frame and a processing device capable of receiving signals regarding the measured electric field. The sensing device is also capable of taking measurements of the electric field from at least a first and second sensing location. The processing device designates the measurement of the electric field from the second sensing location as a reference value when the measurements of the electric field from the first and second sensing locations meet predetermined qualifications and calculates the position of the pointer on a first axis in the reference frame based on measurements of the electric field from the first and second sensing locations and said reference value.

Abstract: The invention is comprised of both a male and female member that join to form a compact flatface connection for fluid transfer typically for low pressure fluid sampling for a wide range of fluid viscosities. The invention relates to the method of achieving several features in one design; high flow, small size, and a flat face valve on the male member. The present invention relates to a fluid transfer connection, and method of producing said connection. More specifically, the present invention relates to a novel combination of features: high flow, and small size for use in a low pressurized fluid or gas connection, where the female member is secured onto the male member and sealed with a flat face type seal.

Abstract: A sealed joint structure for connecting a tube to a male threaded valve or fitting which allows fluid to be sampled or sounds to be amplified more precisely from a location within a fluid vessel, closer to the moving components. The connection includes a valve, a flared tube, a radial seal and a backup spacer. The present invention relates to a novel fluid transfer connection to draw or fill fluid residing in a remotely accessible reservoir from a tube mounted in a male threaded fitting. This fitting is typically mounted to a port on the reservoir. Typically fluid is drawn to analyze the physical and chemical properties of the fluid especially in oil lubricated power transmission devices such as gearboxes and pumps. It is highly desirable to draw, in a timely fashion, a representative fluid sample from the same location in the reservoir, from time to time, in order to accurately trend changes in fluid characteristics that relate to the integrity of the fluid and the lubricated device.

Abstract: A position sensing device for a display device includes an oscillator, a first and second electrode pair, a transparent conductive layer positioned on a display of the display device, first and second differential amplifiers, an amplifier and a processor. The first differential amplifier provides a first signal indicative of distance of the first electrode pair from the second body part of the operator in an x-direction. The output of the second differential amplifier provides a second signal indicative of distance of the second electrode pair from the second body part of the operator in a y-direction. The output of the amplifier provides a third signal indicative of distance of the transparent conductive layer from the second body part of the operator in a z-direction. The processor is operable to generate a three dimensional distance signal based on the output of the differential amplifiers and amplifier.

Abstract: A device for controlling keyboard keys displayed on a display. A three dimensional position sensing device is used to locate a pointing object such as a finger tip hovering over a display screen. A processor moves the displayed keys in corresponding x and y directions responsive to the two dimensional location of the finger tip. The processor also increases or decreases the size of a portion of the displayed keys depending on whether the finger tip is moving toward or away from the display in the z-direction in order to assist the user in navigating a full keyboard in a small display.

Abstract: A position sensing device having an insulating board, a first conductive sensing element, a second conductive sensing element, an oscillator, conductive material, a differential amplifier, and a processor. The first and second spaced conductive sensing elements are on the insulating board. The oscillator generates an oscillating signals and the conductive material is spaced from the sensing elements. The conductive material receives the oscillating signal to create an electric field between the conductive material and the first and second sensing elements. The differential amplifier includes differential inputs that are connected to the conductive sensing elements. The signal levels at the differential inputs vary based on the position of a pointing object of a user relative to the first and second conductive sensing elements. The processor generates a position signal based on an output of the differential amplifier.

Abstract: A probe activated valve system is disclosed that permits easier and safer testing of fluids in a pressurized system. The system has a shell having a valve passage. The valve passage has an end through which the valve passage is fluidly connected to a probe passage. A valve seat is provided at the end of the valve passage. A valve sealing member forms a face seal against the valve seat by compressing a retained sealing member, such as an O-ring. The valve sealing member is moveable from a closed position to an open position, upon insertion of a probe to engage and displace the valve sealing member along the valve passage, such that the valve sealing member is spaced from the valve seat and allows fluid in the valve passage to flow to the probe passage for collection by the probe.
